Sandia National Laboratories

Overview

Sandia National Laboratories is a federally funded research and development center (FFRDC) managed and operated by National Technology and Engineering Solutions of Sandia, LLC (NTESS), a subsidiary of Honeywell International, under contract with the U.S. Department of Energy's National Nuclear Security Administration (NNSA). While Sandia's primary mission encompasses nuclear weapons stewardship and national security research, its quantum computing program has emerged as one of the most technically credible in the U.S. government portfolio. Sandia operates QSCOUT (Quantum Scientific Computing Open User Testbed), a DOE Office of Science user facility that provides open access to a trapped-ion quantum computing platform. QSCOUT is deliberately designed to give researchers low-level hardware access—including pulse-level control—that commercial cloud providers do not expose, making it a uniquely valuable platform for quantum benchmarking, algorithm research, and hardware characterization.

Sandia's core technology thesis in quantum computing rests on two pillars: trapped-ion systems for near-term gate-based quantum computation, and silicon spin qubits as a longer-horizon, scalable modality. The ion trap work leverages decades of atomic physics expertise at the lab, and Sandia is widely regarded alongside IonQ, Honeywell Quantum Solutions (now Quantinuum), and the University of Maryland as one of the world's top trapped-ion institutions. The silicon spin qubit program, conducted in Sandia's world-class MESA semiconductor fabrication facility, positions the lab as a potential enabler of a scalable qubit technology compatible with existing CMOS manufacturing processes. Sandia also runs quantum networking and sensing programs, broadening its relevance to the full quantum information science stack.

Sandia's 'commercial strategy' is fundamentally different from private-sector players: the lab does not sell quantum computing products or services commercially. Instead, its strategic role is as a government-funded research anchor that produces fundamental advances, trains quantum workforce, and provides open infrastructure. QSCOUT serves the DOE's mission to accelerate quantum computing R&D across the national laboratory system and academic community. Sandia's partnerships are predominantly with other national labs (Oak Ridge, Argonne, Lawrence Berkeley), universities, and NNSA mission-program offices. Through DOE's Quantum Systems Accelerator (QSA) and other national quantum initiatives, Sandia is a node in a broader government-orchestrated quantum ecosystem rather than a standalone commercial entity.

In the competitive landscape, Sandia occupies a distinctive niche: it is not competing with IonQ or Quantinuum for enterprise cloud customers, but it is competing—in the sense of vying for relevance and funding—with other national labs and academic centers for DOE/NNSA budget allocations and for scientific influence over the direction of U.S. quantum computing policy. Its defensible position is the combination of QSCOUT's unique open-access hardware model, MESA's semiconductor fabrication capabilities for silicon spin qubits, and deep institutional expertise in systems integration that comes from Sandia's engineering-intensive national security mission.

Leadership

Technology

QSCOUT is built on a linear Paul trap architecture using ytterbium-171 ions (Yb+), the same ion species used by IonQ and a key species at Quantinuum. The system employs laser-based single- and two-qubit gates and is distinguished by its use of Jaqal (Just Another Quantum Assembly Language), an open-source gate-level programming language developed at Sandia that enables fine-grained hardware control. Unlike commercial platforms that abstract hardware away from users, QSCOUT explicitly exposes pulse-level parameters, allowing users to run custom gate sequences, probe noise sources, and test new compilation strategies. This makes QSCOUT less suitable for end-user quantum applications but uniquely valuable for quantum hardware research, error mitigation studies, and benchmarking methodology development.
